“…For TM1 and CM1 E4/E6 polymerization level determination for the first 30 days, values were between 2.8 and 3.1, suggesting compounds with different degrees of aromaticity and aliphatic compounds were present (Fig 1F). Additionally, values below 1.0 could be associated with fractions with greater level of aromaticity and more condensed, such as humic and fulvic acids, indicators of a humus production process [61–63]. These results suggest that for TM1 and CM1 microcosms humus production process took place.…”

A simultaneous treatment of lignocellulosic biomass (LCB) and low density oxodegradable polyethylene (LDPE oxo ) was carried-out using Pleurotus ostreatus at microcosm scale to obtain biotransformed plastic and oxidized lignocellulosic biomass. This product was used as raw matter (RM) to produce biochar enriched with phosphate solubilizing bacteria (PSB). Biochar potential as biofertilizer was evaluated in Allium cepa culture at greenhouse scale. Experiments including lignocellulosic mix and LDPE oxo were performed for 75 days in microcosm. Biotransformation progress was performed by monitoring total organic carbon (TOC), CO 2 production, laccase (Lac), manganese peroxidase (MnP), and lignin peroxidase (LiP) enzymatic activities. Physical LDPE oxo changes were assessed by atomic force microscopy (AFM), scanning electron microscopy (SEM) and static contact angle (SCA) and chemical changes by Fourier transform infrared spectroscopy (FTIR). Results revealed P . ostreatus was capable of LCB and LDPE oxo biotransformation, obtaining 41% total organic carbon (TOC) removal with CO 2 production of 2,323 mg Kg -1 and enzyme activities of 169,438 UKg -1 , 5,535 UKg -1 and 5,267 UKg -1 for LiP, MnP and Lac, respectively. Regarding LDPE oxo , SCA was decreased by 84%, with an increase in signals at 1,076 cm -1 and 3,271 cm -1, corresponding to C-O and CO-H bonds. A decrease in signals was observed related to material degradation at 2,928 cm -1 , 2,848 cm -1 , agreeing with CH 2 asymmetrical and symmetrical stretching, respectively. PSB enriched biochar favored A . cepa plant growth during the five-week evaluation period. To the best of our knowledge, this is the first report of an in vitro circular production model, where P . ostreatus was employed at a microcosmos level to bioconvert LCB and LDPE oxo residues from the agroindustrial sector, followed by thermoconversion to produce an enriched biochar with PSB to be used as a biofertilizer to grow A . cepa at greenhouse scale.

“…It may show that in soil under young shelterbelts the anabolic process is dominated by catabolic. Maryganowa et al [27] and Szajdak et al [28] have proved significant differences of the humic (HA) and fulvic (FA) acids properties estimated by optical, thermal and molecular weight distribution extracted from soil under R. pseudacacia and young shelterbelt. They suggest that the HA from the soil under the old shelterbelt exhibited a higher degree of aromatic condensation and polyconjugation, i.e.…”

The Typic Hapludalfs soils under two old shelterbelts (200 years old) Robinia pseudacacia and Crataegus monogyna, multi species of trees (young shelterbelt - 20 years old) and neighbouring cultivated fields were investigated. The function of shelterbelts of different age and plant composition in agricultural landscape and estimation of biochemical and chemical soil conditions for the decrease of greenhouse gases release from soil to the atmosphere was the aim of the research. In soils under shelterbelts were estimated activities of several enzymes participating in the oxidation-reduction processes, ferric and ferrous ions and the evolutions of gases like N2, N2O, CO2, and CH4. The soils under old shelterbelts characterized higher peroxidase activity than in young shelterbelt and adjoining cultivated fields. However, no significant differences were observed for nitrate reductase activity between old and young shelterbelts. There were proved differences between emission of N2O in soils under shelterbelts and in adjoining cultivated fields. Furthermore, it was observed significant effect of the young shelterbelt on the decrease of carbon dioxide release than in the adjoining cultivated field. The manipulation of the landscape through the introduction of shelterbelts of different age and the composition of plants leads to the modification of biogeochemical soil conditions for N2O and N2 formation and finally decrease of the greenhouse gases evolution from soils to the atmosphere. Thus the creation of new shelterbelts is favourable factor for agricultural landscape.

“…Было обнаружено наибольшее количество липидов в почвах, где прошло более двух столетий с начала роста деревьев. В почвенных образцах, взятых с обрабатываемых полей, которые граничат с лесными полосами различного возраста, содержание липидов и углерода было одинаково и значительно ниже, чем в почве лесополос [7].…”

Цель работы заключалась в изучении характеристик липидов мерзлотных квазиглеевых черноземов юга Витимского плоскогорья с помощью элементного анализа и метода 13 С-ЯМР (Turbic Chernozems Molliglossic). 13 С-ЯМР-структура была определена с использованием метода ядерного магнитного резонанса на ЯМР-спектрометре Bruker АV-600 (резонансные частоты 600,18 МГц -1 Н и 150,93 МГц -13 С), оснащенном датчиком с катушкой для подачи Z-градиентных импульсов. Анализатор CHNS/O Series II от компании Perkin Elmer использовался для определения элементного состава препаратов липидов. Также были получены ЯМР 13 С-спектры препаратов липидов черноземов квазиглеевых. Был проведен исследовательский анализ спектров, в котором были определены сигналы различных групп соединений, таких как этокси-группы, фенольные производные и алкеновые фрагменты. Также были указаны диапазоны химических сдвигов, которые характерны для определенных типов ядер углерода. Было выполнено сравнение содержания различных структурных элементов в пробах. Была обнаружена связь между составом липидов и уровнем влажности в черноземах квазиглеевых. Вероятно, увеличение влажности приведет к увеличению содержания непредельных компонентов. Были обнаружены некоторые изменения в элементном составе липидной фракции органического вещества почвы на глубине 0-20 см. Содержание атомов углерода и водорода немного уменьшилось, в то время как доля атомов азота и кислорода увеличилась. Исследование состава элементов и соотношения атомов вещества позволяет сделать вывод о доминировании алифатической составляющей в верхнем слое черноземов квазиглеевых.Ключевые слова: липидная фракция органического вещества, 13 С-ЯМР-спектроскопия, элементный состав, углерод, чернозем квазиглеевый, юг Витимского плоскогорья Работа выполнена по теме Госзадания № 121030100228-4 «Эволюционно-генетические, биогеохимические и продукционные функции почв Байкальского региона как компонента биосферы, оценка их ресурсного потенциала и разработка технологий рационального использования и охраны».
